.SH NAME
std::basic_stringstream::view \- std::basic_stringstream::view

.SH Synopsis
   std::basic_string_view<CharT, Traits> view() const noexcept;  \fI(since C++20)\fP

   Obtains a std::basic_string_view over the underlying string object. Equivalent to
   return rdbuf()->view();.

.SH Parameters

   \fI(none)\fP

.SH Return value

   A std::basic_string_view over the underlying string object.

.SH Example


// Run this code

 #include <iostream>
 #include <sstream>

 int main()
 {
     // input/output stream
     std::stringstream buf1;
     buf1 << 69;
     int n = 0;
     buf1 >> n;
     std::cout << "1) buf1 = [" << buf1.view() << "], n = " << n << '\\n';

     // output stream in append mode
     std::ostringstream buf2("test", std::ios_base::ate);
     buf2 << '1';
     std::cout << "2) buf2 = [" << buf2.view() << "]\\n";

     // input stream
     std::istringstream inbuf("-42");
     inbuf >> n;
     std::cout << "3) inbuf = [" << inbuf.view() << "], n = " << n << '\\n';
 }

.SH Output:

 1) buf1 = [69], n = 69
 2) buf2 = [test1]
 3) inbuf = [-42], n = -42
